{{Info|A backup of the content of the internal eMMC before anything gets messed is '''mandatory'''.}}

Especially the ''waveform'' partition contains data '''unique''' to your PineNote and is a prime candidate for backup.

But other partitions like U-Boot (need for any operation of the device) or the un-partitioned space at the beginning containing the GPT partition table (and presumably the VCOM setting for the e-ink display and maybe device mac addresses) contains data you may wish to backup.

Depending of your personal level of data hoarder you may want to backup more than this or even just everything (the large ''userdata'' partition is supposed to be able to be repopulated as empty space by Android)

In any case it is easier to restore/extract data from a backup than not having one if you need one.

=== Manually using rkdeveloptool ===
Dorian has some nice [https://github.com/DorianRudolph/pinenotes notes regarding the PineNote]

Don't forget to install a patched U-Boo for reading beyond 32MB and to respect the 2GB limit/bug of the current rkdeveloptool as per his notes

Build rkdeveloptool:

git clone https://gitlab.com/pine64-org/quartz-bsp/rkdeveloptool.git
cd rkdeveloptool
mkdir build
cd build
cmake ..

Download mode
Enter the download mode by placing the pen as pictured below. A magnet placed where the pen's cap is should also work (haven't tried). I guess the dot on the case also indicates the position of the sensor.

placing pen on the back

<code>lsusb</code> should now recognize the PineNote as:

2207:350a Fuzhou Rockchip Electronics Company USB download gadget

{{Warning|this process is very new! Proceed at your own risk.}}

See [https://github.com/m-weigand/pinenote-debian-recipes/releases/tag/v0.1 instructions on this artifact]. It will instruct you on extracting the rootfs into an empty ext4 partition. This can be done from Linux or Android. Further instructions on building your own rootfs [https://github.com/m-weigand/pinenote-debian-recipes can be found here].

=== Automated backup using a script and rkdeveloptool ===
[https://github.com/talpadk/pinenote-backup pinenote-backup] is a python script for detecting the partitions and automating the backup of partitions or the whole disk.

It also requires a patched u-boot but automatically handles the 2GB limit by splitting up larger reads into smaller ones

=== Using the factory Android installation ===
TODO

=== Using a user installed Linux ===
A Linux installed to the cache partition should be able to easily backup everything over WiFi or to a USB stick/disk using ''dd''.

However the user would need to backup the cache partition themself (if they want that).

And more importantly they would only be getting the backup ''after'' they started playing with the content of the eMMC.
